Frequency synthesis with the Commodore Amiga for research on perception and memory of pitch

Discusses the potential of the Commodore Amiga as a digital synthesizer for research and demonstration in psychoacoustics and memory. Economy, ease of use, flexibility, portability, and accuracy outweigh disadvantages of narrow bandwidth, narrow dynamic range, and storage limitations for many applications encountered in pilot research and education. The Amiga also bears serious consideration for psychoacoustic studies requiring frequencies below 4000 Hz and modest signal-to-noise ratio, as exemplified by an implementation for research in absolute judgment, similarity scaling, and sequential pattern tracking.
